IR & 12v Triggers

[Deleted]

Will the UMC-1 turn my Escient on/off? I'm confused on "IR"
I assume the 12v triggers will work.
Manual states: IR Connections-
The direct IR input jack on the back panel of the FireBall is for controlling FireBall from a wired IR distribution system such as a Xantech system.
This connection must be an IR signal with a 36kHz carrier using an 1/8” mono or stereo connector.
The IR input jack provides 12V power. This means that you can directly connect a 12V IR receiver (like the Xantech series 291 units) to the FireBall using a 1/8” stereo connector.

I made a decision to get the UMC-1 & undecided on UPA-7 or UPA-5

Hi texzick-

You don't want to plug a trigger out of the UMC into an IR jack on your Escient! There will be a nice whiff of fragrant smoke and little else. ;-)

Trigger out supplies 12v out to turn on an amp, close a relay to move curtains or screens, etc.
IR in lets you hide a piece of gear in a cabinet and use an external IR receiver to get the commands to it.

Thanks Markd,
I had a brain lock-up & should have known that. (12 vdc vs 12 vac-36khz)

No problem. Just wanted to make sure you didn't let the magic smoke out. ;-)

I have a question about 12v triggers. In the user's guide, it states that anything plugged directly into the wall should not be switched with the trigger connection. So, I can't use the trigger output to power up my amp when I turn on the Pre/pro? I have the amp plugged into the wall on it's own curcuit and was told not to run it through a power strip.

I didn't hook up the trigger because of this issue and am curious which conditioners/power strips have a high enough current rating to plug the amp into.

Hey sr71, I use an APC H-15 power conditioner and have all my gear plugged into it. I am also triggering my amps from the UMC-1. All is working fine.

Initially after receiving the UMC-1, I had plugged the amps directly into the wall and the triggering worked fine.

So regardless of whether the amps are plugged directly into the wall or into a "non current limiting" power conditioner, it works. The key is in bold above. AFAIK, most, if not all, power strips would be current limiting so you're looking at conditioners such as the APC, or Monster or such. I would look for the term above when doing your research. YMMV..

Where did you see this in the UM? I just searched the PDF on line and did not see any reference. .... That would be a very strange (and painful) restriction.

I think I remember seeing something similar to that in the Power Amp manual, but the OP got mixed up on what it was saying not to do. I believe it was saying not to trigger the amp using a device that was plugged directly into a 120V outlet. This would avoid accidently sending 120V AC into the Amp's trigger connection.

It will always be safe to use the UMC-1's trigger outputs with any Power Amp's trigger input.

Yeah, I wasn't sure exactly what it meant. It says that in both the MMC-1 and the LPA-1 manual, pages 24 and 18, respectively.

I have the MMC-1 plugged into a 3800 jule strip, since it only requires 2 amps of current. The LPA-1 is plugged into the wall, at least until I can budget for a quality conditioner.

Thanks for the replies, guys.

Having the MMC-1 plugged into the 3800 joule strip is fine. I would keep the LPA plugged directly into the wall outlet. All of the Emotiva amps have built-in filtering and surge protection. There is no reason to plug the amp into a power conditioner; and it may even have a negative impact on the dynamic response of the amp. Many power conditioner will reduce the dynamics on your amp. Emotiva recommends that you NOT use power conditioning.
